Refill device for dispensing a cosmetic product

ABSTRACT

A device for refilling a first container, fitted with a threaded first neck and a vaporization head, includes a second container for a liquid, a connection component including a first bearing plate for engaging the first neck and a second bearing plate engaging the second container, a median wall including a central orifice, and a means of closing the second container or the central orifice. The connection component engages an axially movable component capable of sliding inside the connection component, to form a valve, the movable component being able to move, under the action of an axial constraint, from a closed position “F” to an open position “O”, or, under the action of a spring, from the position “O” to the position “F”. The movable component includes a radial projection for engaging the first neck so that the first neck exerts an axial constraint on the radial projection.

FIELD OF THE INVENTION

The invention relates to the field of cosmetic product dispensers. More particularly, embodiments of the invention relate to the field of perfume dispensers, including refillable dispensers.

BACKGROUND OF THE INVENTION

Perfume bottle refills typically include containers or bottles that comprise a threaded neck, closed with a threaded plug. Similarly, refillable dispensers typically include a spray head screwed into a bottle that comprises a threaded neck. To refill the dispenser, the usual way of proceeding is to unscrew the vaporization head and to decant the refill content manually, after unscrewing its plug.

Using a refill is desirable when the quality and price of the dispenser with head render it essentially a non-disposable object. Conversely, the value of a refill for the refillable dispenser is related more to the value of its content than to that of the container forming the refill, with the result that, since it is of little intrinsic value, the dispenser refill is typically thrown away or recycled once empty.

Given the fact that the neck of the refillable dispenser is typically small in size, some skill or manual dexterity may be required in order to decant or transfer the perfume from a refill or feeder bottle to the bottle of the dispenser. The usual consequences of a decanting operation, unless one is very skillful, may be on the one hand a loss of product contained in the refill, which is often a very expensive perfume, and on the other hand, a potential to spill the product on clothes or hands, with the risk of having a persistent and lingering odor associated with this operation, since the product or perfume may have been able to spread and impregnate a cloth material.

A system for filling a secondary bottle from a main bottle is known through French Patent Application No. 00 11082. But a system of this kind has a certain complexity both in manufacture and implementation.

There remains a need for a means that is both cost-effective and practical, in other words easy to implement by any user, so as to avoid the drawbacks associated with conventional systems.

BRIEF SUMMARY OF THE INVENTION

According to the various embodiments of the invention, a device for refilling a first container, typically a perfume bottle, that is fitted with a first typically threaded neck and a vaporization head, includes:

-   -   a) a second container intended to contain a liquid product,         typically perfume, to be transferred into the first container,     -   b) a means of engagement having an axial direction and forming a         typically watertight component for connecting the first and         second containers, the connection component including a first         typically threaded bearing plate for engagement with the first         neck and a second typically threaded bearing plate for         engagement with the second container or with a typically         threaded second neck of the second container, the first bearing         plate and second bearing plate being arranged on either side of         a typically horizontal median wall, including a central orifice,         so as to bring the first and second necks opposite each other,         and to form a means of transferring the product contained in the         second container to the first container, and     -   c) a means of closing up the second container or the central         orifice.         -   It is characterized in that:         -   1) the connection component engages with an axially movable             component able to slide inside the second neck in axial             travel, the movable component being able to move, under the             action of an axial constraint, from a closed position “F” in             which the central orifice is capped, to an open position “O”             in which the central orifice is open, then to move, under             the action of a return means, typically a spring, from the             position “O” to the position “F”, the movable component             engaging the connection component so as to form a valve and             so as to form the closure means,         -   2) the movable component includes a peripheral part forming             a drive means, typically a radial projection, intended to             engage with the first neck or upper edge thereof, the first             neck or upper edge thereof exerting on the drive means or             the radial projection the axial constraint when the first             neck engages with the first neck typically by screwing the             first neck into the first bearing plate, and comes axially             closer to the median wall,         -   3) the movable component includes a central part capable of             engaging the connection component for the purpose of forming             the valve.

Indeed, on one hand, product decanting or transfer is limited to two basic operations, with:

-   -   the vaporization head being unscrewed in order to disengage the         first neck of the first container, the first container         corresponding to the dispenser to be refilled,     -   then the refill device simply being screwed to the first neck.

Decanting or transfer of product without loss and without mess is thus possible.

On the other hand, a device according to embodiments of the invention forms a valve which opens automatically as soon as the refill device is screwed onto the first neck corresponding to the bottle to be filled, and which re-closes automatically as soon as the refill device is unscrewed, which is extremely practical.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the Figures, aspects of the invention relate to a device (1) for refilling a first container with liquid product. The device provides a connection component for connecting the first container with a second container that holds liquid to be filled into the first container.

According to aspects of the invention, a radial projection may form a peripheral ring (50). Any type of radial projection may be suitable insofar as the radial projection allows the automatic axial displacement of the movable component when the first container is screwed to the device (1). The movable component is displaced in a direction towards the median wall of the device (1) which makes it possible to move the valve (12) from the closed position “F” to the open position “O”.

According to an embodiment of the invention such as illustrated in all the Figures, except for FIGS. 8 a to 9 b, the connection component may include an axial projection around the central orifice, the axial projection typically forming a tube portion integral with the median wall so as to form all or part of the transfer means.

As shown in FIGS. 7 a and 7 b, the tube portion may include an upper tube portion located above the median wall.

As shown in FIGS. 3 a, 5 a, 6 a, 10 a and 11 a, the tube portion may include a lower tube portion located below the median wall.

Whatever the embodiment of the invention, the central part may engage with the central orifice or with the tubes (43, 43 a, 43 b) so as to form the valve. This engagement, which allows an axial displacement of the movable component relative to the connection component, is preferably a watertight engagement, which may require the use of tightness means, typically gaskets.

As shown in FIGS. 3 a, 5 a, 6 a, 7 a and 8 a, the central part may form a central tube, the central tube being able to slide in the central orifice or in the tube portion.

As shown in FIGS. 3 a, 5 a and 6 a, the central tube of the movable component may engage with the lower tube portion, the central tube being able to slide inside the lower tube portion. As shown in FIG. 3 a, the lower tube portion may include a bottom including an orifice, the bottom being integral with a central component including an upper flap valve and an axial rod anchoring, typically by a snap-on process, the central component to the lower tube portion, and typically to the bottom, the upper flap valve forming an upper stop for the central tube, the central tube being open at its two ends. In this way, when the axial constraint is exerted on the radial projection, and opening is formed between the fixed upper flap valve and the upper end of the central tube that form the valve, the opening thus ensures flow of the liquid product.

As shown in FIG. 5 a, the lower tube portion may include a bottom including an orifice, and the central tube may include a lower flap valve anchored to the central tube by a rod or an axial wall, the lower flap valve being spaced out axially from the lower end of the central tube, in such a way that the lower tube portion forms, typically by its lower end, a lower stop for the lower flap valve, and in such a way that, when the axial constraint is exerted on the radial projection, a lower end (12′a, 12′b) is formed between the movable lower flap valve and the lower end of the lower tube portion which form the valve, the lower opening (12′a, 12′b) thus ensuring a flow of the liquid product. The rod or axial wall may form a unitary component with the movable component. The lower flap valve may either form a unitary component with the rod or axial wall, as shown in FIG. 6 a, or may be anchored, typically by being snapped on, to the rod or axial wall, as shown in FIG. 5 a.

According to aspects of the invention, the return means may be a spring, typically a helical spring, located either between a lower end of the central tube (5′) and the bottom, or between the radial projection and the median wall.

According to another embodiment of the invention, such as shown in FIGS. 7 a and 7 b, the central tube of the movable component may engage the upper tube portion, the central tube being able to slide outside the upper tube portion, the central tube including only an upper part (51 a). In this case, the upper tube portion may be closed at its upper end and includes at least one lateral orifice, in such a way that the lateral orifice is able to be closed or opened as a function of the axial displacement of the movable component, typically by its end (510).

According to another embodiment of the invention, such as shown in FIG. 8 a, the connection component does not include an axial projection around the central orifice. The central tube is capable of sliding in the central orifice, and comprises a lower flap valve anchored to the central tube by a rod or an axial wall. The lower flap valve is spaced out axially from the lower end of the central tube and the return means (6) or spring may be placed between the radial projection and the median wall or radial extension thereof, in such a way that the median wall or radial extension thereof forms a stop for the lower flap valve. Additionally, when the axial constraint is exerted on the radial projection, a lower opening (12′a, 12′b) is formed between the movable lower flap valve and the median wall or radial extension thereof which form the valve. The lower opening (12′a, 12′b) thus ensures flow of the liquid product.

According to another embodiment of the invention, such as shown in FIGS. 9 a and 10 a, the central part may include a lower flap valve anchored to a rod or an axial wall. A connection means (514) anchors the rod or axial wall to the radial projection, the lower flap valve being stopped against the median wall or against the radial extension thereof or against a lower tube portion. In this way, when the axial constraint is exerted on the radial projection, a lower opening (12′a, 12′b) is formed between the movable lower flap valve and the median wall or radial extension thereof or the lower end of the lower tube portion, which form the valve. The lower opening (12′a, 12′b) thus ensures flow of the liquid product.

Whatever the embodiment of the invention, the central part of the movable component or of the axial projection may include an axial separation wall (52, 45), so as to form a conduit (13) for the liquid distinct from the conduit (14) for the air. The liquid (13′) and air (14′) flows have to run in counterflow, with the liquid flow running from the second container towards the first container, and the air flow running from the first container towards the second container. The upper openings or the lower openings (12′a, 12′b) form distinct openings, that is, distinct upper openings and/or distinct lower openings (12′a, 12′b).

Although the devices in these Figures are shown in the vertical position, in practice, they depart more or less from the vertical, with the result that, due at least in part to the presence of an axial separation wall (45), the liquid product will tend to flow through the conduit (13) and the displaced air will tend to flow through the other conduit (14), as shown in FIG. 4 b, which greatly facilitates the flow by gravity of the liquid product from the second container towards the first container (3). In FIG. 4 a, the flow or flux (13′) of the liquid product in the conduit (13) has been shown by an arrow.

As shown in FIG. 3 a, the axial separation wall may be an axial separation wall (45) forming or including the axial rod.

As shown in FIG. 5 a, the axial separation wall may be an axial separation wall (52) forming or including the rod or an axial wall (513).

As shown in FIG. 7 a, the axial separation wall may be an axial separation wall (45), typically a central separation wall (434) forming a partition wall of the upper tube portion.

As shown in FIGS. 8 a and 9 a, the axial separation wall may be an axial separation wall (52) typically formed by the axial wall (513).

As shown in FIGS. 8 a and 9 a, the lower flap valve may be anchored to the axial wall, the axial wall typically being extended by an upper axial wall (515), the axial wall and the upper axial wall (515) forming the axial separation wall (52).

As shown for example in FIG. 1 c, the connection component and the movable component may include a least one tightness means (15) to provide a watertight valve.

As a shown in FIG. 1 b, the device (1) may include a removable cap (8) that engages the first bearing plate so as to protect the movable component when the device is not in use. The cap also avoids unintentional application of an axial constraint on the movable component.

By way of example, the axial travel between the positions “O” and “F” in the various embodiments may be typically from about 2 mm to about 6 mm, and preferably, from about 3 mm to about 5 mm.

According to aspects of the invention, the second container may be a bottle with a threaded neck, of plastic or glass material, or a tube made of plastic material.

As shown in FIGS. 12 a to 12 c, the plastic tube (2′) may be a tube (2″) making a unitary component with the connection component (4).

Embodiments of the invention, on the one hand, address the problems posed in a straightforward, efficient and cost-effective manner. On the other hand, a variety of embodiments are provided, which can be adapted to various situations, some including a very limited number of components and thereby being highly cost-effective.

Lastly, aspects of the invention make it possible to transfer, by gravity, a perfume contained in a rigid feeder bottle forming a second container, and to do so while maintaining control over the quantity to be transferred. The receiving container, or first container, has only to be unscrewed to automatically close the valve of the device.
